v1.2-Works with low and high resolution phones NOW!
The sender and receiver must have an identical random key file on their SD cards, this file should be generated and exchanged in person in advance of communication. Future versions may support additional less secure algorithms without this requirement.
OTP is unbreakable when used with a truly random key ("Communication Theory of Secrecy Systems", C. E. Shannon, 1949).
Caesar Cipher Full Version is now free !

In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. For example, with a left shift of 3, D would be replaced by A, E would become B, and so on. The method is named after Julius Caesar, who used it in his private correspondence.
Enter a password/key and then enter your message - the app will then encode it as well-scrambled gibberish! Highly recommended for spies of all experience levels as well as for those who simply enjoy the allure of cryptography. It is simple, effective, and sure to confuse the bad guys.
This is my first app; I hope you like it. I'd feel great if you could give it a positive review ;). Constructive criticism appreciated as well!
Your favorite app developer,
This is one of the oldest cipher encryption algorithms of which we have historical record. It is a substitution cipher monoalphabetic.
With this application you can encrypt your messages with a key of your choice, and immediately forward them via SMS thanks to direct commands to send and phonebook access.
Choose whether to encrypt or decrypt the message
Enter a number from 1 to 26 as a key (a key must be known by your recipient)
Enter the text
Click on the crypt (Important!!)
If you send text messages, click on heading to select a number. Not required for sending e mail (requires internet connection)
Copy the text from the SMS or email messages (hold down the text, and then click on the top copy)
Open the application and click on the "decrypt and reply"
Paste the text by clicking the left button
Insert the key, and click on "decrypts"
- Ability to send multiple sms
- Language support (anyone willing to translate a few lines of text in your application, you can send me an email)

Please note this cipher is completely insecure and can be cracked with pencil and paper in a matter of minutes. This app is just for fun and should not be used for important secure communications.
You can also use the app to check if encrypted text is encrypted with a Caesar cipher by placing the encryption in the plaintext box and cycling through all letter shifts.
Accepts common punctuations, numbers upper and lower case alphabets (76 shifts),
